Application mea February 14, iea. "serieu No.' 9,133.

This invention relates to storage batteries and more particularly to theconstruction of the covers thereof.

An important object of the invention is to provide a cover which may bebrought into sealing engagement with the jar without the necessity ofemploying sealing compounds of any character.

A. further -object of the invention is to provide a cover Vconstructedso that the box of the battery is protected against the action of `acidsand fumes particularly as regards the upper surface of such box.

A further object of the invention is to provide a device of thischaracter which, when employed in combination with a battery unitmounting` such as is described in my Patent No. 1,580,596, granted Apr.13, 1926, for storage batteries, will afford a complete seal bothbetween the ar and the cover and the cover and the battery post againstthe leakage of acid or fumes without employing a sealing compoundtherewith.

These and other objects I attain by the construction shown in theaccompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure 1 is afragmentary perspective view of a battery embodying covers constructedrin accordance with my invention and shown as having applied thereto alink mounting constructed in accordance with the application abovementioned;

Figure 2 is a transverse sectional view showing the construction of thecap where the associated wall of a battery jar upon which the cap isapplied abuts against the wall of the battery box;

Figure 3 is a view showing they construction of the cap where theassociated wall of the jar to which the cap is applied abuts a secondjar, and Y Figure 4 is a perspective of the cover removed, a portion ofthe cover being broken away to show the construction thereof.

Referring now more particularly to the drawings, the numeral 10generally indicates a battery box wall and 11 the side walls of the opentop jars employed within the box for the reception of the batteryelements. In accordancev with my invention, a cover is provided uponwhich the usual provision is made for a vent cap 12 and battery linkconnector and post mounting indicated at 13. This cover embodies adepending flange 14 extending into and closely fitting the inner face ofthe side wall 11 of the battery jarl at its upper portion 15 and havinga lower portion 1t so formed that it loosely engages within the batteryjar and opposes the walls of the battery jar in spaced relation thereto.Between these upper and lower portions of the flange, the outer surfaceof the ange is formed with a continuous groove 17 in which is seated agasket 1S of soft rubber or other suit-able material. course, be of suchsize that it will beV com pressed lin the operation Yof inserting theflange of the cover into the upper end of the batteryrjar and willafford a sealing engagement. between the ange and battery jar.

The side edges of the cover project beyond the depending flange to lformside wall flanges 19 and 20. `Where the wall of the jar to which theflange 14 is opposed abuts a second battery jar as in Figure 3, theflanges 19 are employed and are of the same width as the thickness ofthe battery jar so that they do not projectbeyond the side edges ofthisbattery jar and a neat joint will be formed beneath the covers. Vherethe portion of the jar opposed by the flange 14 This gasket will, of

is opposed to the box wall 10, the ianges 20 are employed and theseflanges are of a width equal to the combined thicknesses of the batteryjar wall 11 and the wall 10 of the box. The appearance of a completebattery equipped with covers of this character may be determined by aninspection of Figure A1 from which itis seen that the entire yupper edgeof the box is covered by the flanges and the covers with their flangescombine to form a flat smooth surface for the upper'face ofthe completedbattery.` YSuch av surface is readily kept clean and free from any acidYaccumulation such as might pass from the vent opening 21. The covers arefurthermore much more easily applied and removed than the ordinary coveremploying thel use of a plastic seal and may be as cheaply or morecheaply produced than such covers.

Since the` structure herebefore set forth 1s obviously capable of aslight change witheuch including n (impending Hangs iltting within thebnftely jul' and having a gasket abutting the opposed 'faire ol thebuttery 3:11', said flange having upper and loWeL- porn tions, the upperportlon closely lnterlolly fitting the jul', the lower portion beingspaced from the Wall of the jm' and 0ppos ing the sume, Said flangehaving a. g1 'o0ve intermediate said upper 21ndV lower portions 10 forthe reception of said gasket.

In testimony whereof I hereunto affix my signature.
